Table 5. Live birth rates of the patients depending on the compaction status and transfer day of the embryo. Pearson's Chi-squared test was used to analyze the differences for significance.

	Early compaction group	Control group	p
Live birth following 3. day embryo transfer (n, %)	57 (out of 186) (%30.6)	39 (of 189) (%20.6)	0.026*
Live birth following 5. day embryo transfer (n, %)	61 (out of 203) (%30.0)	47 (of 198) (%23.7)	0.154
Live birth (n, %)	118 (out of 389) (%30.3)	86 (of 387) (%22.2)	0.01*
